Now more and more thin electronic products, many mobile phones, tablets, computers are using a thin aluminum oxide as the product of the shell. Using laser Q-switch in thin aluminum plate marking guide potential, easily lead to deformation of the material, abaxially produced "convex hull", directly affect the appearance. The parameters of MOPA laser pulse width smaller, which can make the material easy to deformation, shading is more delicate and bright white. This is due to the laser MOPA use the pulse width parameter can make laser stay at the material time becomes shorter, and sufficiently high energy can remove the anode layer, so for thin aluminum plate surface stripping anode processing, MOPA laser is a better choice.
